bugfix: don't say 'not yet set' in planting form

PT: https://www.pivotaltracker.com/story/show/51457917

Maco found this. The problem was that if you had a blank planting date,
and then re-edited the planting, it would say "not yet set" in the form
field, then die when it later tried to convert that to a date.

I replaced Miles's planted_at_string stuff in the model with a simpler
parse_date method in the application helper.
